Patent FR-2325821-A1 (FR)
Title: Drive for heavy duty high torque press - has two or more wheel operating hydraulic jacks depressing cover
IPC: F03C1/30
Filed: 1975-09-26
Abstract: The drive wheel rotates on the central axle (10). The wheel rim is shaped into a number of equally spaced grooves (8) on the central web and similar grooves on the flanges (15). The hydraulic jacks (5) (5') pivot around the fulcrum (6) (6'). The jack is fitted with a semi-circular end (7') which rides on the central web of the wheel and a pair of rollers (14) which roll on the flanges. The jacks are operated out of phase by the hydraulic circuit so that one jack operates after another. This gives a constant drive to the wheel. The jacks are kept in position by the springs (17).

Title: Slow rotation system for heavy shafts - uses ratchet wheel displaced via levers by hydraulic jack, with spring return
Inventor: BELPERIN GERARD
IPC: F01D25/34
Filed: 1975-10-28
Abstract: The rotor or shaft is provided with a ratchet wheel (1). A pawl (4) is mounted on a pivot (5) at the end of a lever (7). The lever (7) is mounted on a pivot (8) and its other end is connected to a sliding block (13). The sliding block (13) is supported in bearings (15) (16) and attached by the rod (14) to the piston rod (18) of a hydraulic jack (19). When the jack (19) pushes the block (13) to the right the pawl (4) is pushed to the left and engages the teeth of the ratchet wheel imparting a counter-clockwise rotation. The spring (22) returns the block (13) to its original position so that the motion can be continuously repeated.

Title: Prefabricated staircase in two sections - has each section supplied with banister and vertical and horizontal step components slotted and bolted into position
IPC: E04F11/035
Filed: 1975-11-20
Abstract: The prefabricated staircase is formed in two separate parts. It comprises an upper and lower section which are assembled either in place in the building or before leaving the factory by bolting together two adjacent ramps. Each section contains its own vertical and horizontal step components and banister. They are slotted into position and screwed together by extended bolts located between two parallel lugs which fit into recesses formed in the adjacent section. The staircase assembly is constructed so that the top step or the lower section slots into a locating groove formed at the base of the upper section.
Patent FR-2333703-A1 (FR)
Title: Automatic winding of small parts onto wire - to replace expensive hand jigging of parts prior to electroplating
IPC: B65B15/00
Filed: 1975-12-03
Abstract: Automatic machine for attaching workpieces possesses a head, e.g. bolts or screws, to a wire. The screws are fed down a chute to a sepg. wheel provided with peripheral notches, and the screws are loaded stepwise, one after the other, into the notches. The stepwise rotation of the sepg. wheel carries the screws below a threading tube, via which metal wire travelling freely from a spool is wound twice round each screw. During the last quarter of the winding cycle, i.e. half a turn, the threading tube is automatically lifted by a cam so one screw wound on the wire leaves the machine via an exit channel and the wire is wound round the next screw. One rotating shaft drives the threading tube, and also uses a ratchet for the stepwise rotation of the sepg. wheel. Used, e.g. in electroplating small parts, e.g. the chromium plating of screws. Barrels are normall used for electroplating small parts due to the prohibitive cost of and jigging the parts onto a wire, but barrel coatings are inferior to those obtd. using jigs. The invention automatically assembles the pats onto a wire for electroplating.

Simple cheap process using small sized equipment, and only requiring use of a flocculating agent. Gives solid prods. having a low water content. These can be used in the prodn. of fertiliser or cement.

Title: Automotive diesel engine with swirl chamber - has low pressure fuel supply system delivering to chamber around valve which is accelerated to raise pressure
Inventor: SOUBIS JEAN-PIERRE
IPC: F02B19/02
Filed: 1977-06-23
Abstract: The engine has a swirl chamber(7) in the cylinder head(4). A narrow passage(6) between the cylinder and the swirl chamber is controlled by a valve(11) operated from the camshaft(14).

Title: Formation of semiconductor heterostructures and junctions - by deposition of acceptor or donor doped indium oxide and subsequent heating
IPC: H01L21/363
Filed: 1977-08-23
Abstract: The prepn. is for a single junction between regions having different conductivities within a semiconductor substrate and a surface heterostructure. The method is esp. applicable to photodiodes and solar cells where a transparent or no reflecting electrically conducting surface is required. Preparation simplifies normal techniques by diffusion of impurities from the surface deposition such that the formation of the junction becomes automatic. Two basic stages consist of deposition of an acceptor or donor doped indium oxide to form the heterostructure and subsequent heating of the substrate such that impurities migrate into it to form the required junction.
